| The high efficient and quick dissolution of rhodium is a key part and a recognized technical problem in the field of rhodium metallurgy. The process of dissolving rhodium by electrochemical method was studied. Effects of factors, such as the liquid-solid ratio, the diameter of the electrode and the concentration of rhodium in solution on rhodium dissolution rate were investigated. The experimental results show that, the ratio of liquid-solid ratio is reasonable between 15~90 mL/g, the dissolution rate of rhodium powders is positive correlated with the electrode diameter and is negative correlated with the rhodium concentration. Under the optimum reaction conditions, the dissolution rate is 1 g/h |
